Intersil High Power Integrated LED Driver ISL78100
brief introduction: ![]()
Intersil has introduced a high-power integrated LED driver with the ISL78100, which can be used in applications such as display backlights and body electronics. The ISL78100 is specifically designed to withstand harsh automotive environments.
The ISL78100 is flexible enough to be optimally configured to drive from 1 to 8 high-brightness LEDs while operating in boost, buck or single-ended primary inductor converter (SEPIC) settings. The ISL78100 also has two ways to control the brightness level of the LED, either by DC bias current or by using an external PWM signal to more precisely control the color temperature of the LED.
In addition, designers can choose integrated protection from the ISL78100. An error monitor that is isolated from the input current can be used to disconnect the input supply and protect against overload conditions.
The ISL78100 also features thermal compensation and a load disconnect switch. The device's temperature compensation greatly increases the life of the LED. A built-in thermal control circuit monitors the thermistor voltage and adjusts the LED's bias current. This high level of integration allows designers to avoid the use of costly separation protection schemes.
With an efficiency of up to 92%, the ISL78100 extends battery life in a variety of applications when the engine's ignition switch is turned off.
The device is AEC-Q100 rated and fully compatible with TS16949, including a Process Capability Evaluation Index (CPK) for higher process requirements. The ISL78100 is rated for the automotive temperature range (-40° C to +105° C) and is available in a tiny 4mm x 4mm x 0.9mm QFN package and is the smallest integrated high power LED driver available.
Pricing and availability
The ISL78100 is available in a 20-pin QFN package with a unit price of $1.32 for 1000-piece quantities and $1.39 for a roll-to-roll configuration with 1000 units.
